A EEG APPARATUS WITH ECG ARTIFACT ELIMINATION DEVICE AND THE METHOD THEREOF

摘要

An electroencephalogram inspection apparatus having an electrocardiogram noise elimination device, and an inspecting method thereof are provided to detect and remove an electrocardiogram noise included in an electroencephalogram of a single channel. An electroencephalogram inspection apparatus having an electrocardiogram noise elimination device includes an electrode unit(100), an amplifying unit(130), a filter(170), an analog/digital converting unit(190), a calculation unit(200), and an output unit(330). The electrode unit has electrodes for detecting electroencephalogram. The amplifying unit amplifies the electroencephalogram signal detected in the electrode unit. The filter filters the amplified signal. The analog/digital converting unit converts the filter signal into a digital signal. The calculation unit calculates the signal received from the analog/digital converting unit. The output unit displays an output signal of the calculation unit. The calculation unit has an R-wave estimation unit(210), and an electrocardiogram estimation and elimination unit(260). The R-wave estimation unit detects an R-wave of a spike shape from the received signal from the analog/digital converting unit, and detects an impulse which is synchronized with the R-wave. The electrocardiogram estimation and elimination unit estimates and eliminates an electrocardiogram signal based on the output signal of the R-wave estimation unit and the received signal from the analog/digital converting unit.
